I have given the listening test for the level 8 test, and I'm assuming it's similar for the level 9 test. His listening score was by far his lowest score. This was several years ago, but from what I remember I had to read aloud a fairly long, detailed, and boring story and then the test asked questions about specific details, and I think even the order of the details ("this happened first, this happened second, this happened third, this happened fourth, etc" in a list followed by several more sentences and then they'd ask "what happened third?").
I remember not being too worked up over the score being lower because I didn't think the test was testing anything useful. My day to day experience with my son was that he was a good listener and had a phenomenal ability to pay attention. In addition, his WISC IV scores (from that same year) showed excellent working memory.
My rule of thumb about these things is that if test scores do not match what you know to be true about your child, then there is probably something wrong with the scores. However, it sounds like you have concerns about her hearing, listening, and attention that go well beyond what happened on the test. I agree with aeh that it may be time for an evaluation.
